Arvind co-leads Mayfield’s engineering biology follow and is founder and enterprise advisor at IndieBio. He was the primary investor in breakout bio corporations resembling Geltor, Synthex, Prime Roots, NotCo, Prellis, New Tradition, DNA Lite and Memphis Meats.

Local weather within the final decade has been unprecedented in some ways, none of them good.

Wildfires in California have consumed whole cities; hundreds of miles away, New Yorkers inhale the ashes. Throughout Europe and Japan, flash floods wreak widespread devastation. All of us see the movies on YouTube and CNN. And we shrug.

The not too long ago launched sixth Intergovernmental Panel on Local weather Change report concluded that human-created local weather change is going down quicker than we thought, calling it a “code-red alert.” At simply 2 levels hotter than at this time, one estimate predicts greater than 300,000,000 climate-related deaths globally by 2100. And that’s the optimistic estimate. International warming is overwhelming and feels not possible to repair. What the hell can we do?

Like a lot of you, I’m an optimist. Humanity has come to the boundaries of nature many occasions previously, and has overcome them with know-how. We have now at all times tailored ourselves to our surroundings; altering our know-how and habits attributable to environmental change is a part of our historical past.

Regulation will assist incentivize firms to wash up, however solely know-how can clear up the intractable drawback of sustainably giving us what we need. Inconsiderate consumption introduced us local weather change, however it is usually true that aware consumption can get us out of it.

How can we use capitalism to get rid of greenhouse gasoline emissions worldwide? Comply with the carbon. That leads us to the three predominant bottlenecks on the highway to net-zero carbon emissions.

What follows is essentially a high-level overview of big and sophisticated industries. I’ve purposely not noted granular particulars so we might tackle the overarching points.

Electrification: 36 gigatons CO2 emitted

TAM: $7 trillion

International carbon utilization is highest in vitality manufacturing as we burn coal, oil and pure gasoline to energy our vehicles, cities and trade (sure, coal remains to be mined and burned in 2021). That’s a whopping 36 gigatons of CO2 emissions per yr. Why can we nonetheless burn coal? It’s low-cost, on-demand, common, moveable, an order of magnitude extra environment friendly than lithium-ion batteries, and far safer.

But it surely must be eradicated, very quickly.

The IPCC report discovered that 89% of worldwide CO2 emissions come from fossil fuels. Additional, it tells us we should minimize these emissions in half over the subsequent decade or danger a 1.5-degree Celsius enhance in common world temperatures.

At present, wind and photo voltaic can’t produce electrical energy 100% of the time; generated vitality have to be saved somewhat than simply dumped if unused, as it’s carried out at this time. There are various methods of manufacturing clear vitality at this time, together with nuclear, tidal, hydroelectric, geothermal and different means. Fusion is advancing yearly.

Civilization was born alongside the sheep and cow, however 10,000 years later, the sheep, cow and pig are killing us. They emit 10% of worldwide greenhouse gases, and world demand for meat is skyrocketing.

We are going to want greater than double at this time’s clear vitality output to service rising demand. However till we will retailer this vitality and use it in vehicles, boats, airplanes and extra, clear vitality manufacturing won’t get rid of the necessity for oil and coal. Power storage is the principle bottleneck for a worldwide electrical economic system. We want greater, safer and cleaner batteries that can be utilized in all places from the grid to our vehicles to our houses, and preserve the lights on after we want them most.

You and I gained’t be shopping for these batteries, however they may energy all the things we do purchase. From vehicles to the cargo ships that ship them to the airplanes that carry us, they may all ultimately be electrical. Boeing simply ordered 100 electrical planes from Coronary heart Aerospace, wherein it additionally invested. The world’s first electrical cargo ship, the Yara Birkeland, constructed by Marin Teknikk, is scheduled to have its maiden voyage quickly.

There aren’t any fewer than a dozen electrical plane corporations and 6 dozen electrical car corporations. However the bottleneck for these efforts to scale and change all fossil gas planes, ships and vehicles with equal efficiency is a humble battery able to delivering sustained, excessive energy output over an extended time frame. With out that elementary development, these corporations will keep within the conceptual stage for a very long time.

Sadly, lithium-based battery know-how nonetheless solely has one-tenth the utmost vitality density of gasoline (which is round 50 megajoules per kilogram). It isn’t sufficient. The closest we will get with lithium-ion know-how is the lithium-air battery, which has a theoretical vitality density of 40 megajoules per kilogram, however new electrolytes should be invented for it to work. Like Chuck Yeager breaking the sound barrier to usher within the supersonic period, we have to break via this density barrier to energy our inexperienced future.

Latest research have demonstrated that melanin, our pores and skin pigment, has additionally proven promise as a potent cathode that may make rechargeable sodium batteries a risk. This might allow large-scale “salt” batteries that can be utilized to create a protected and clear grid storage answer. Researchers have additionally used viruses to create nanolayers of various components to make higher-performance cathodes. Different traces of analysis have proven that batteries pushed by enzymatic catalysts can doubtlessly use sugar water to slowly cost your automotive or home with bio-electricity. Not one of the options above are inside a decade to market; all are within the analysis stage.

The winners of the electrification wars will combination these applied sciences throughout industries and supply shoppers with a seamless, fantastic expertise. From quick wi-fi charging of electronics and automobiles to self-adapting nationwide electrical grids, an electrified world can be quieter, environment friendly and clear. I’m excited concerning the prospect of residing in a totally electrical world.

Rematerialization: 10.2 gigatons emitted

TAM: $12 trillion

Each object within the room you’re sitting in was made unsustainably and reeks of carbon emissions. The cement ground, couch, eating desk, desk, fridge, sink, chairs, even the partitions contribute to local weather change. Shoppers haven’t any alternative; they’ll’t purchase inexperienced, and we have to change this.

Sturdy items and our constructed atmosphere alone account for greater than 10.2 gigatons of CO2 emissions yearly, or almost one-third of whole emissions. The heights of soiled trade should be toppled and rebuilt from scratch with a brand new objective in thoughts: Sustainable manufacturing for a whole lot of years to come back.


International cement manufacturing emits almost 2.5 gigatons of carbon dioxide per yr. There are dozens of inexperienced cement corporations now attempting numerous approaches to eliminating CO2 emissions from cement and concrete. At IndieBio, I invested in Carbix, an organization that takes CO2 emissions and makes use of them to make olivine cement. They’ve made a number of bricks and are years from the market.

The principle barrier for many inexperienced cement formulators is proving equal structural efficiency. Attending to scale is pricey. Nonetheless, a number of corporations promising greener concrete are coming to market within the subsequent few years.


Making metal and aluminum is energy-intensive. Actually, aluminum is referred to by many commodity merchants as “vitality in stable type.” Powering our foundries with clear vitality and decreasing their carbon utilization will assist get rid of 8% of emissions.


Timber are our largest carbon sinks. They suck in CO2 from the air and exhale the oxygen we breathe. So why can we nonetheless minimize them down?

Hopefully, quickly we gained’t must. Corporations are utilizing flax and different pure fibers to create bio-composites which are stiffer than metal and lighter than wooden, or growing sustainable bamboo for exterior constructing panels. Others are experimenting with mushroom mycelium to develop whole buildings.

Leather-based and materials

Cows contribute 7.1 gigatons of CO2 per yr to world warming, a full 14.5% of the full. We don’t simply eat them, we use their pores and skin rather a lot. Leather-based is in all places, from footwear and couches to purses and clothes. We have to change this materials if we’re to get rid of cows from our provide chain.

Thankfully, a dozen corporations are making headway into eliminating plastic and leather-based from trend. All are discovering super traction with client corporations seeking to present their shoppers with vegan and sustainable merchandise.

Materials like polyester are manufactured from petrochemicals. Fermentation applied sciences excel at making oils from sugar water through the use of algae or yeast as a manufacturing unit. Fermentation is scalable and exists at this time, whereas a more recent know-how known as cell-free synthesis is being utilized to those identical issues. We will anticipate new inexperienced materials within the subsequent 5 years.

Industrial chemical substances

Break down oil and also you get an inventory of unpronounceable names that make a lot of our world. These chemical substances are utilized in engines, antifreeze, cosmetics and even meals. To get rid of any want for oil, these merchandise have to be changed via fermentation, which converts sugar into chemical substances.

The sugar can come from corn and even waste CO2 in chimneys. Cells don’t must be alive both, as cell-free synthesis permits the enzymes themselves to do the work. An enormous variety of corporations have been began to remake all these chemical substances via types of fermentation and synthesis.

Rematerializing our planets with sustainable, carbon-neutral sources can take away as much as 10 gigatons of emissions from our economic system. Our homes and all the things inside them will ultimately grow to be carbon-neutral via rematerialization. I’m enthusiastic about breaking this bottleneck to progress as a result of it naturally results in higher merchandise for everybody.

Meals: 3.6 gigatons C02 emitted

TAM: $10 trillion

The primary slide of a presentation I gave to elucidate the brand new meals revolution depicted cavemen with spears being mauled by an enormous prehistoric bear. The purpose? Protein is necessary sufficient to die for. As we transitioned from searching to farming, our society reorganized round cities and the division of labor.

Civilization was born alongside the sheep and cow, however 10,000 years later, the sheep, cow and pig are killing us. They emit 10% of worldwide greenhouse gases, and world demand for meat is skyrocketing. Over the previous six years at IndieBio, I’ve invested in Clara Meals, Geltor, Memphis Meats (now Upside Meals), NotCo,and lots of others to reinvent agriculture via fermentation, plant-based formulations and cell-based tradition.

These startups reinvented acquainted meals like burgers, mayonnaise, popcorn shrimp, egg whites, poke bowls, sausages and hen wings. As prosperous societies started consuming extra processed meals, meals grew to become merchandise: Cows grew to become burgers, pigs grew to become bacon and chickens are actually nuggets. A legion of food-as-product corporations have adopted of their footsteps and there are whole conferences devoted to them. “Meals is scorching” is an understatement in Silicon Valley.

Having been part of the meals revolution from its earliest days, I’m struck by the magnitude of those revolutions as soon as they actually get going. I’m additionally cautious of revolutions that stall. Cell-based meals ought to be available on the market subsequent yr and shoppers will get to determine for themselves if the revolution is for them. So the ultimate form and type of the world as soon as the revolutions roll via society and grow to be the brand new regular just isn’t straightforward to foretell.

I’m a fan of historical past, so I look into the previous to see the place we’re going subsequent. My mom’s recipe for curry hen is an effective place to begin. It requires hen thighs with the bone in, chopped. If I wish to make a low-carbon, animal-free model of that recipe, I’d have to make use of one thing aside from hen, however what? Simply’s cell-based hen nuggets? No, breaded hen nuggets gained’t work, nor would soy options. Past Curry? My mother wouldn’t approve.

Biofarming actual meals

For agriculture to be reinvented for everybody, not simply the 1%, we should make meals. Actual, pure meals. Steaks, hen breasts and thighs, bone-in meats and spare ribs. Not a processed model of those merchandise, however substances to make whole-food dishes.

Meals 3.0 is biofarming. Biofarming must clear up for style and healthful diet. Scrumptious meals with no processing aside from mother’s recipe. Regenerative agriculture will allow carbon-neutral greens and crops if we can assist farmers get their yields excessive sufficient to show a revenue whereas a discipline is fallow for a season. Quite a few applied sciences are serving to to realize this.

We aren’t F’d but

Bloomberg not too long ago reported that there have been over 5 million deaths a yr globally from local weather change-related occasions from 2009 to 2019. That’s 1 in 10 deaths on the planet. Since we don’t monitor this statistic (we monitor warmth stroke, drowning, landslide, suicide, and the issues that immediately kill us), nor different results like folks not having youngsters and excessive nervousness, it’s not possible to know the true magnitude of distress local weather change will deliver. How far will we let this go earlier than all of us act? What number of extra must die?

The brand new regular doesn’t should be this fashion. Scientists can select to use their work to resolve the paradox of carbon and manufacturing. Traders can select to place cash into corporations rebuilding our world to be light and inexperienced. And entrepreneurs can select to construct corporations that reshape our carbon economic system for the best alternative in historical past. The above highway map represents the power to erase almost all carbon emissions by humanity.

We’re removed from doomed. Collectively, we’ll all construct and we’ll all combat for our future.
